In-Situ Slurry Wall Formation with the SoilSaw? Barrier System

This new technology was designed to form high-quality "formed-in-place" barrier walls in soil in a more continuous and uniform manner than the two-step, excavate and replace, processes of conventional slurry trenching. Soils in the path of the device are pulverized in-situ and liquified by high-energy jets of a permeability modifying grout. The hardware then passes through the liquified soil under the pull of gravity. The soil/grout mixture hardens to form a plastic diaphragm wall. Walls can be formed from a variety of materials.
